Abstract

An apparatus and method for seamlessly providing voice and data services to a user through an access terminal in a mobile communication system including a heterogeneous service & mobility gateway (HSMG) for an interworking service between a circuit network and a packet network, and various access networks overlapping each other. The access terminal notifies the HSMG that a voice call is received, if the access terminal that accessed a packet network receives a voice call. The HSMG sends a direction request to a circuit network upon receiving the notification indicating that the voice call is received. The access terminal directs to the circuit network and registers a new location upon receiving the direction request. The HSMG sets up an incoming voice call to the access terminal after the registration of a new location.

Claims

1. A method for providing voice and data services to an access terminal for simultaneously supporting a circuit network and a packet network in a mobile communication system that supports an interworking service between the circuit network and the packet network, the method comprising:

receiving, by the access terminal, a paging message for one of a voice call and a packet data call while the access terminal monitors a particular network;

selecting, by a heterogeneous service and mobility gateway (HSMG), an optimal access network based on at least one of a service requirement relating to one of the voice and the packet data, and an access state of the access terminal;

notifying the access terminal of the selected access network by the HSMG for an interworking service between the circuit network and the packet network; and

redirecting, by the access terminal, to the selected access network.

2. The method of claim 1, wherein the service requirement is selected according to a service type, a service profile for an access terminal, required quality-of-service (QoS), and a wireless environment.

3. A system for providing one of a voice and packet data through an access terminal for simultaneously supporting a circuit network and a packet network by interworking the circuit network with the packet network in a mobile communication system with a plurality of access networks overlapping each other, the system comprising:

the access terminal for receiving a paging message for one of a voice call and a packet data call while the access terminal monitors a particular network; and

a heterogeneous service &

mobility gateway (HSMG) for selecting an optimal access network based on at least one of a service requirement relating to one of the voice and the packet data, and an access state of the access terminal, and notifying the access terminal of the selected access network by the HSMG for an interworking service between the circuit network and the packet network,

wherein the access terminal redirects to the selected access network.

4. The system of claim 3, wherein the service requirement is selected according to a service type, a service profile for an access terminal, required quality-of-service (QoS), and a wireless environment.
